In other words, you want to count how many 1st of the months there are from
today until 5/31/2009?

What should happen on 6/1/2010? Should the benefit year automatically
rollover to the next year. In other words, on 6/1/2009 the benefit year
ending date automatically changes to 5/31/2010.

Employee benefit period is 6/1-5/31. An employee pays 20% of our cost for
medical insurance. Since there may be 2 or 3 paychecks in a month, we
divide
the annual cost by 26 paychecks per year.

Is there a function that recognizes 6/1, 7/1 etc so I could calculate how
many months remain in the benefit year* cost of insurance * 20%? Thanks.
